Western societies are confronted with a number of challenges caused by the increasing number of older citizens. One important aspect is the need and wish of older people to live as long as possible in their own home and maintain an independent life. As people grew older, their social networks disperse, with friends and families moving to other parts of town, other cities or even countries. Additionally, people become less mobile with age, leading to less active participation in societal life. Combined, this normal, age-related development leads to increased loneliness and social isolation of older people, with negative effects on mental and physical health of those people. In the AGNES project, a home-based system has been developed that allows connecting elderly with their families, friends and other significant people over the Internet. As most older people have limited experience with computers and often special requirements on technology, one focus of AGNES was to develop with the users novel technological means for interacting with their social network. The resulting system uses ambient displays, tangible interfaces and wearable devices providing ubiquitous options for interaction with the network, and secondary sensors for additionally generating carefully chosen information on the person to be relayed to significant persons. Evaluations show that the chosen modalities for interaction are well adopted by the users. Further it was found that use of the AGNES system had positive effects on the mental state of the users, compared to the control group without the technology.

The thesis claims that an experiential approach to design really does promise the possibility of scientific design of everyday life. The purpose of this thesis is to show the promise. René Descartes conceptualized the classical formulation of a mind-body dichotomy. Various resulting and unbalanced dichotomies, such as subjective-objective, internal-external, experiential-practical and so on, raise serious concerns surrounding the concept of design. The thesis raises a crucial issue about the imbalance between technological and human concerns in the context of human-computer interaction, an imbalance that has been caused partly by the mechanistic aspect of informatics and its impact on designing human computer interaction. The thesis first explores the origin of design as a distinct activity during the industrial revolution, and reviews the tide of design history from then until today. The brief review of design history indicates that design is not merely the skill of making things or presentations. This gives direction to how design can be positioned in our modern information society. Second, the author starts a critical discussion about ordinary design approaches that, it is suggested, may have hindered true human-centred design, and then introduces an alternative approach to design and research, which the author calls Human-Experiential Design. Third, the notion of Tangible Presence in Blended Reality Space is introduced. The conceptual grounding that illustrates the experiential approach to interaction design is discussed. Fourth, the thesis presents use cases and provides examples of Human-Experiential Design in specific practical contexts. The concrete examples suggest that the emphasis on ‘balance’ or appropriate blending is very important in the development of better interactive systems for health, capitalizing on seamless combinations of the virtual and the physical in Blended Reality Space. As exemplified in the thesis, the human-experiential approach, striving for optimal combinations of tangibility and evoked presence, offers a promising tool in designing for special needs groups such as elderly people with some cognitive weaknesses, and children undertaking physical rehabilitation programmes. It is suggested that such virtual-physical blends will release human beings from the strain that existing perceived dichotomies bring. Finally, the author concludes by offering a way forward, a way that is neither subjective nor objective but rather a meaningfully integrated blend of the dichotomies, which responds to the question of what it means to be human.

We discuss issues relating to presence arising from the recent evolution of tangible interaction techniques as an alternative interaction paradigm to the familiar WIMP-based Graphical User Interfaces (GUIs). The intersection of sensory, cognitive and also emotional aspects in such interfaces takes us a significant step further than GUI techniques. We introduce our concept of Tangible Presence in Blended Reality Space, and its study as an emerging weaving of HCI and presence research. An experimental study is then described, which examined the influence of three key factors in the way blended realities may be implemented: tangibility, viewpoint and avatar identity. The study examined the effect of manipulations of these factors on rated presence and self-presence. Our findings emphasize the importance of tangibility for presence, but suggest that presence and self-presence are unrelated phenomena. Finally, as critical concerns in future work to design and implement blended reality spaces for a variety of purposes, context sensitivity and usability issues are discussed.

Increases in computation power have allowed design software to become more complex. At the same time, big data and artificial intelligence, question the traditional tools of the human designer. Morphogenetic (concerned with the beginning of the form of an object) prototyping provides a method for designers to control this complexity by separating the design into pseudo developmental stages to enable the manipulation of its development at different stages. This paper investigates the tools, processes, theory and systems that would be needed to simulate this design experience. Through this process a katana sword is selected as the metaphor for the design experience to relate the affordance of cutting to the simulation of a pseudo biological sub division. A sword prototype is used to identify appropriate gestures to map to biological behaviours in order to trigger the simulation of staged pseudo biological processes in the design model. Finally, the tangible user interface (TUI) tool based on the katana sword is refined and future work is outlined. Refereed/Peer-reviewed

This book explores how our lives and social interactions have become split between two intertwined, but not integrated, realities: the physical and the digital. Our sense of presence in the here and now has become fragmented, and yet earlier design approaches reinforced the problem, rather than leading to improvements. The authors address these issues by laying out a new human computer interaction (HCI) design approach – human-experiential design – rooted in a return to first principles of how people understand the world, both consciously and unconsciously. The application of this approach to the design of blended reality spaces is described in detail. Examples and scenarios of designing them to overcome the problems inherent in a variety of mixed reality settings are provided. Human-Experiential Design of Presence in Everyday Blended Reality will appeal to undergraduate and graduate students and researchers in interaction design, psychology, HCI and computer application studies, as well as practicing interaction designers and computer professionals. It will also be of interest to communication, media and urban design students, and to all readers with an interest in the technology-mediated future.

Background: Interactive computer play is a promising tool in rehabilitation of children. There is still little research presented in this field, and thus sparse evidence for its effectiveness. It is however evident that children, parents and therapists are in favour of this form of training and that modern motor learning theories fit very well with the concept of practising in interactive computer-based environments. There is nevertheless a need for development of new systems purposely designed for rehabilitation and this work faces substantial challenges. Objectives: In this paper we briefly present our ongoing research regarding interactive training for children with sensorimotor disorders, and reflections about challenges in the development of new interactive systems for motor rehabilitation. Methods: Interactive training using low-cost motion interactive games was evaluated with three-dimensional kinematic motion analysis, clinical motor tests, physical activity monitors, interviews and gamin...

The aim of this chapter is to propose a new way to meaningfully bridge the dichotomy between technological and human concerns in the context of E-health systems. We see ‘Design’ as having the responsibility to ensure that humans can fulfill themselves in the world of things (or technology). First, this chapter raises issues surrounding human-centered design of E-health, caused by three major dichotomies which create imbalances that have caused a lack of true human-centered-ness: (1) the human-user dichotomy, (2) the virtual-physical dichotomy, and (3) the experiential-practical dichotomy. Second, this chapter reframes a categorization of customer, user, person and human, which allows us to discover new aspects of ‘humans’ and of true ‘Human-centered design’. Third, the concept of Tangible Presence in Blended Reality Space, an emerging integration of HCI concerns and Mediated Presence research, is introduced. Finally, the author proposes a new way of approaching human-centered design, what they call Human-Experiential Design, through which the experiential-practical dichotomy is effectively blended. The author believes that this view will be significantly important in attempts to go a further step in the development of better E-health, capitalizing on seamless combinations of the virtual and the physical in blended reality. Such blends will release human beings from the strain that existing dichotomies bring. Refereed/Peer-reviewed

The present paper starts with a crucial discussion about the imbalance between technological and human concerns in the context of human-computer interaction, an imbalance that has arisen partly from the mechanistic aspect and its impact on interaction design. We then introduce the concept of Blended Reality Space, interactive mixed reality environments where the physical and the virtual are seamlessly combined and affect each other. The conceptual grounding and practical examples that illustrate our approach to interaction design are then discussed, adopting a standard figurative representation of blends. This helps understanding the role of blending that meaningfully bridges unbalanced separations between cognition and action, and the physical and the virtual. As a concrete example, the AGNES project, which is aimed at developing “user sensitive home-based systems for successful ageing in a networked society”, is introduced. We believe that the emphasis on ʻbalanceʼ or appropriate blending is very important in the development of better interactive systems for health, capitalizing on seamless combinations of the virtual and the physical in Blended Reality Space.

Blended Reality Space is our term for an interactive mixed-reality environment where the physical and the virtual are intimately combined in the service of interaction goals and communication environments aimed at health support and rehabilitation. The present study examines the effect on rated presence and self-presence of three key factors in the way blended realities may be implemented for these purposes. Our findings emphasize the importance of tangibility for presence, but suggest that presence and self-presence are unrelated phenomena. These findings will be incorporated into design principles for our planned work to develop free movement-based interactions for motor rehabilitation as well as blended-reality spaces for collaboration between hospitals, care organizations, and the home.

There are growing needs for communication and collaboration on different managerial and operational levels in healthcare. One trend that has been noted in our modern society is the move of nursing care from traditional hospitals to the patient’s own home. The aim of this paper is to suggest a conceptual solution for healthcare collaboration and to provide an intersectional approach to go beyond that which was possible today and towards better communication and collaboration tomorrow. First, this paper discusses specific issues in communication and collaboration arising from the reality gap between media-physical spaces, then proposes an overview of a new way to approach problems for which conventional design methods offer no clear solution. The paper is thus mostly a description of a problem area, and a general approach to addressing it. We conclude with a description of future needs for further research on collaborative healthcare.
